51424-66-9 Usage
Purification Methods
The acid is purified by recrystallisation from Me2CO, Et2O/pentane, or AcOH, dried in a vacuum oven (105o/20mm) and sublimed at high vacuum. [Staunton & Eisenbram Org Synth 42 4 1962, Steiger & Reichstein Helv Chim Acta 20 1404 1937.]Check Digit Verification of cas no
The CAS Registry Mumber 51424-66-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,4,2 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.Calculate Digit Verification of CAS Registry Number 51424-66:
(7*5)+(6*1)+(5*4)+(4*2)+(3*4)+(2*6)+(1*6)=99
99 % 10 = 9
So 51424-66-9 is a valid CAS Registry Number.
